Reaction Steps

A mixture of tert-butyl 4-((3-nitropyridin-2-yl)amino)piperidine-1-carboxylate (8.5 g, 26.4 mmol) in hydrogen chloride (4 M solution in methanol, 50 mL) was stirred at room temperature for 3 hours. It was concentrated under reduced pressure to give crude 3-nitro-N-(piperidin-4-yl)pyridin-2-amine hydrochloride (6 g, 23.2 mmol, 88% yield) which was used without further purification.
